Six cartridges of
I-125 seeds were received on 11/6/2006. During the inspection of the cartridges, a bent seed was found and removed from one of the cartridges. One additional cartridge was inspected by removing the seeds and reloading the cartridge. The remaining cartridges were visually inspected. No contamination was found on any of the cartridges.
The seeds were implanted in a patient at approximately 10:00 on 11/8/2006. After the procedure, residual activity was found on one of the cartridges. A urine assay on the patient was performed and a low level of activity was found (about four times background). A spectrographic analysis confirmed the activity as I-125.
The licensee is performing a dose assessment. The seed manufacturer was notified and stated that they would notify the state of Illinois.
